David Walton and Majandra Delfino Expecting Second Child

Cecilia Delphine received an extra special first birthday present: she’s going to be a big sister!

Majandra Delfino and David Walton are expecting their second child in December, their rep confirms to PEOPLE exclusively.

“We are very excited. We think our 1-year-old Cecilia is excited too, but she can’t talk yet so we can’t be sure,” the couple joke to PEOPLE in a statement.

Although the new parents will have their hands full with two under two, Delfino — best known for her role on Roswell and starring in the upcoming sitcom Friends with Better Lives — admits Walton, 34, has babies on the brain.
“I walked in on my husband talking about a third child and we haven’t even had a second yet. What the hell you guys,” Delfino, 32, joked on Twitter earlier this month.

Fortunately, fatherhood suits Walton — who recently wrapped a storyline on New Girl and will next be seen in the new series About a Boy and two movies, Think Like a Man Too and Break Point — very well, according to his wife.

“Having a baby makes people’s true selves shine through,” Delfino Tweeted. “Turns out my Pekingese is a total a-hole and my husband is a saint. Who knew.”

Loved her as Maria on Roswell! I agree with the above, the Roswell cast is having a lot of babies! Katherine Heigl, Colin Hanks, Shiri Appleby and now Majandra’s having her second! Wish there was more Roswell on!
